What is a Chemical Reaction? Evidence of Change—ChemTopic™ Lab Activity

We live in a world of change, including complex chemical changes that may be hard to identify. With the What is a Chemical Reaction? Evidence of Change—ChemTopic™ Lab Activity, examine the chemical properties of hydrochloric acid and copper(II) chloride, identify the types of reactions that occur, and determine whether the law of conservation of mass applies to chemical reactions in a series.
